You and your classmates create 19 tapestries to sell at the PTA auction to raise money for your school. In order to pay for the materials you bought to make the tapestries, you need to sell each of the tapestries for $2.00. When transporting the tapestries to the auction, one of your parents accidentally drops five of the tapestries in the street and they are run over by a Community Transit bus. What is the new minimum price you need to set for the remaining tapestries in order to pay for the materials?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
